Ihe embodiment of my invention illustrated in Figures l through 6 comprises three terminal posts 20, 2 I, 22, adapted to receive conductor terminals. The terminal post 22 comprises a tubular body portion 23 of generally oblong rectangular section having opposite walls 24, 25 and opposite walls 26, 21 at right angles to the walls 24,

25. The wall 26 is made in halves, one half 26 being integral with the wall 24 and the other half 29 being integral with the wall 25. The wall 21 is made in halves, one half 30 being integral with the wall 24 and the other half 3i being integral with the wall 25. Interal with the wall 24 is a U-shaped loop 32 forming an aperture 33. The right hand leg of the loop 32 has its outer surface disposed in contact with the inside surface of the wall 25 near the top of that wall. The lower end 35 of the right hand leg of the loop 32 is adapted 5 to form a shoulder which is on the same level as a shoulder 34 extending inwardly from near the top of the wall 24. 'I'he end 35 of the loop 32 may be provided with a tongue |19 extending laterally therefrom, through an aperture in 10 the wall 25, the tongue having its end bent over against the wall 25 to clamp the loop 32 to the wall 25.

The shoulders 34, 35 serve to limit the upward movement of a U-shaped detent means 36. The l5 detent means 36 has an arch-shaped bight 31 merging into legs 33, 39, fitting slidably within the tubular body portion 23. The detent means 36 is provided at the top oi.' the bight 31 with a protuberance 40, here shown as of approximately 2o senil-cylindrical form, which may be struck up out of the bight 31. The protuberance 4I) has its cylindrical axis at right angles to the axis of the arch-shaped bight 31 and at right angles to the axis of the aperture 33, the protuberance 40 25 being cooperable with the aperture 33 and a conductor terminal insertable in that aperture. The detent means 36 is provided with two lateral projections 4|, 42, which are desirably struck out from the opposite lateral surfaces of the detent 30 means, and are adaNed to engage the shoulders 34, 35.

The wall 26 is provided with a conductor terminal receiving aperture 44, formed by recessing the longitudinalabutting margins of the wall halves 35 23, 29, and the wall 21 is provided with a conductor terminal receiving aperture 43, formed by recessing the abutting longitudinal margins of the wall halves 30, 3l. The apertures 43, 44 are in axial alinement. The upper inside surface of 40 the arch-shaped bight 31 of the detent means 36 is in substantial alinement with the upper margins of the apertures 43, 44, and is adapted to serve as a seat for a conductor terminal inserted in the apertures 43, 44. 45

A U-shaped detent means 45 is provided for cooperation with the conductor terminal receiving apertures 43, 44 and a conductor terminal insertable therein. The detent means 45, in this instance, includes a bight 46 having a generally 50 flat top surface, merging into the legs 41, 48 adapted to ilt slidably within the tubular body portion 23. The bight 46 is provided with a protuberance 43, in this instance of approximately #mi-cylindrical form, the axis oi.' the cylinder 55 being at right angles to the common axismf the conductor terminal receiving apertures 43, 44.

Upward movement oi.' the detent means 45 is limited by engagement of the bight 46 with the lower ends of the legs v38, 39 of the detent means 38. A spring 58 is provided for biasing the detent means 45 upwardly against the detent means 38, and hence biasing the detent means 38 against the shoulders 34, 35. The -spring 58 is disposed within the tubular body 23 and has one end in engagement with the under surface oi the bight 48 and the other end in engagement with an insulating plate The terminal post 22 is provided with feet 52, 53 formed by extensions on the wall halves 38, 3|, bent outwardly at right angles from these wall halves. with feet 54, 55 i'ormed by extensions of the wall halves 28, 29, bent outwardly at right angles from these wall halves. The bottoms of the feet 52, 53, 54, 55 are adapted to abut the top of the insulating plate 5|. The terminal post 22 ls held to the insulating plate 5|, as will be hereinafter described.

. The terminal post 22 is adapted'to be electrically connected to and hold in position a cartridge fuse 56 having terminals, here shown as ferrules 51, 58. 'I'he ferrule 58 cooperates with a .terminal clip 59 which in this instance comprises a at portion 88 provided with two downwardly extending anges 8|, 82. 'I'he flange 8| is formed by bending the end of the clip at right angles to the iiat portion 88, and the flange 6| may have plane outer and inner surfaces. On the other hand, the flange 52 is formed-to have an inside surface which is arcuate, to generally yaccommodate the arcuate lateral surface of the ferrule 58, as may be seen in Figure 6, the ferrule 58 being there indicated in dotted lines. The arcuate flange 82 is integrally joined to a U-shaped loop 53 concentric with and overlying the loop 32, and forming an extension of the wall 25 of the terminal post 22. The fuse clip 59 is thus resiliently mounted, so that when the fuse 55 is removed the clip 59 will move downwardly and assume a position such for example as shown in dotted lines in Figure 2. It will therefore be apparent that the underside of the iiat portion 88 of the fuse clip is adapted to engage the fiat end of the ferrule 58, whereas the inside surface of the plane flange 8| engages the cylindrical surface of the ferrule 58 and biases the upper end of the fuse, by reason of the resilience of the loop 68 and the joint between it and the ilange 82, into the arcuate seat formed. by the inside surface of the arcuate flange 82.

The fuse clip 59 also biases the iuse downwardly so that the end of theferrule 51 is pressed into engagement with a contact 84, here shown as a. generally square plate.

The contact 54, in this instance, forms an integral part of the terminal post 2|. The terminal post 2| comprises a tubular body 85 of generally rectangular oblong cross-section, having opposite walls 68, 81 and opposite walls 68, 89 at right angles to the walls 68, 81. The wall 58 is made in halves, one half 18 being integral with the wall 88, and the other half 1| being integral with the wall 51. The wall 89 is made in halves, one half 12 being integral with the wall 88, and the other half 13 beingintegral with the wall 81.

The walls 88, 81 are integrally joined at their upper ends by a U-shaped loop 14 providing an aperture 15. The wall 81 is integral with the contact 84 extending at right angles from the I'he terminal post 22 is also provided lower end of the wall 81 extended. The contact 84 therefore also serves as a foot for the terminal post 2|.

Cooperable with the aperture 15 and a conductor terminal insertable therein, is a detent means 18 having an approximately semi-cylindrical protuberance 11, the detent means 18 being also in other respects identical with the detent means 45 of the terminal post 22. However, the detent means 15 instead of having its upward movement limited by engagement with another detent means, as in the caseof the detent means 45, has its upward movement limited by vshoulders 18, 19 extending inwardly from the walls 55, 81 near the top of these walls and their junction with the loop 14. The detent means 18 is biased upwardly by means of a spring 88, one end of which engages the underside of the detent means 16, as in the case of the detent means 45, and the other end of which engages the'insulating plate 5|. It will be evident that the terminal post 2| is designed for the accommodation of but a single conductor terminal.

The terminal post 28 comprises a tubular body portion 8| of generally rectangular oblong crosssection having opposite walls 82, 83 and opposite walls 84, 85 at rightangles to the walls 82, 83. The wall 84 is made in halves, one half 88 being integral with the wall 82, and the other half 81 being integral with the wall 83. The wall 85 is made in halves, one half. 88 being integral with the wall 82, and the other half 89 being integral with the wall 83. The walls 82, 83 are integrally joined at their tops by a U-shaped loop 98 providing an aperture 9|.

Cooperable with the aperture 9| and a conductor terminal insertable therein is a detent means 92 provided with an approximately semi-cylindrical protuberance 93. The detent means 92 is also in other respects identical with the detent means 38 of the terminal post 22, 'Ihe detent means 92 has its upward movement limited by shoulders 94, 95 extending inwardly from the walls 82, 83 near the top of these walls.

The walls 84, 85 of the terminal post 428 are provided with 'conductor terminal receiving apertures 99, |88 formed respectively by recessing the longitudinalvabutting margins of the wall halves 88, 81 and the wall halves 88, 89. 'Ihe upper inside surface of the arch-shaped bight of the detent means 92 is in general alinement with the upper margin portions of the apertures 99, |88.

Cooperable with the apertures 99, |88 is a detent means 98 provided with a semi-cylindrical protuberance 91 and otherwise also identical with the detent means 45. The detent means 98, 92 are biased upwardly by a'spring 98 engaging the under surface of the bight of the detent means 98, as already explained in connection with the terminal post 22. The other -end of the spring 98 engages the insulating plate 5|.

The terminal post 28 is provided with feet |8|,' |82 formed by extensions on the wall halves 88, 88 respectively, bent outwardly at right angles from these wall halves. The bottoms of the feet |8|, |82 are adapted to engage the insulating plate 5|. 4

The terminal posts 28, 2| are integrally joined by a bridge |83 extending at right angles b`etween the lower end of the wall 83 of the terminal post 28 and the lower end oi the wall 85 oi the terminal post 2|. The bridge |83 is provided with lateral extensions |84-, |85 serving as additional feet, adapted to abut the insulating plate u 5| and aiding in supporting both of the terminal posts 20, 2|.

The terminal posts 20, 2|, 22 may be held in position on the insulating plate 5| by an insulating plate |06 provided with apertures |01, |06, |09, spaced and formed so as to snugly receive the terminal posts 20, 2|, 22. The insulating plate |06 consequently overlies the feet provided on these terminal posts. 'Ihe insulating plate |06 is also provided with an aperture I0, adapted to receive the terminal 51 of the fuse. .The fuse terminal 51 in this instance has a diameter somewhat greater than the width of one of the narrower walls of the terminal posts, such as the Wall 24 of the terminal post 22, and the aperture ||0 therefore has two of its opposite sides recessed to form the arcuate margins If desired, the stock from which the insulating plate |06 is made, may be provided with equally spaced apertures, all of the form of the aperture ||0, so that any one of these apertures may be used for the reception of a fuse terminal such as 51. The nature of the apertures obviously, however, depends upon the diameter of the fuse terminal.

The insulating plates 5| and |06 may be clamped together in any suitable manner, to hold the terminal posts 20, 2 22. In this instance the plates 5|, |06 are disposed in a metallic channel ||2 having a bottom ||3 and flanges ||4, ||5. The flanges are provided with ngers ||6 which may be clinched over the top of the insulating plate |06 to firmly hold the parts together. If desired, a spacer ||1 of approximately the same thickness as the feet of the terminal posts 20, 2|, 22 may be provided between the insulating plates 5|, |06.

The terminal posts such as 20 and 2| are clearly shown, described, and claimed in my Patent Number 2,122,030, dated June 28, 1938. V

In Figure 3 is shown in what manner the terminal posts cooperate with a conductor terminal, a conductor terminal IIB being shown having an annular furrow ||9 in a cylindrical portion of the conductor terminal. The conductor terminal is provided with a frustro-conical end |20, which is adapted to cam the detent means 16, downwards, and` as the conductor terminal 8 is inserted into the terminal receiving apertures, the protuberance 11 snaps into the furrow H9. The conductor terminal may be swedged to the conductor contained therein, as indicated by the swedge indentations |2|.

It will of course be evident that conductor terminals such as H8 may be inserted and held by the respective detent means in any one or more or all of the conductor terminal receiving apertures of the terminal posts 20, 2 22. Thus a variety of circuit connections may be made, and circuits completed which may or may not include the fuse 56 as may be desired.

It will be apparent that the terminal post 22 may be made of sheet metal, the body portion being completely formed in channel-shaped halves, one half including the loop 32 and the other half the loop 63, along with the fuse clip portion 59 completely formed as an extension of the loop 63, before the halves of the terminal post are brought together so that the longitudinal abutting edges of the channel-shaped halves form lines of registry |22, |23. 'I'he detent means 36, 45, which are also desirably made of sheet metal, and the spring 50, may then be positioned in the body of the terminal post 22, as already described. While the terminal post 22 is illustrated as made of two separate pieces of sheet metal, the terminal post 20 is made of a single piece of sheet metal and the terminal post 2| is also made of a single piece of sheet metal. Moreover the terminal posts 20, 2|, together-may be made of a single piece of sheet metal, as illustrated. The halves of the body of the terminal 2| are completely formed in the channel-shape hereinbefore described and the loop 14 is formed by bending the channel-shaped halves toward each other until the longitudinal edges meet in lines of registry |24, |25. The terminal post 20 is formed in the same manner, the longitudinal edges of the channel-shaped halves meeting in lines of registry |26, |21.

From the foregoing it will be evident that the number of terminal posts, the number of conductor terminal receiving apertures in any given post, the number of fuses and the arrangement of the posts and fuses may be greatly varied.

Referring now to the embodiment of my invention illustrated in Figure '7, there is here shown connection means comprising three terminal posts |28, |29, |30. The terminal post |30 comprises a tubular body portion |3| of generally oblong rectangular cross-section having opposite walls |32, |33 and opposite walls |34, |35, at right angles to the walls |32, |33. The wall |34 is made in halves, one half |36 being integral with the wall |32, and the other half |31 being integral with the wall |33. The wall |35 is made in halves, one half |36 being integral with the wall |32 and the other half |39 being integral with the wall |33. Integrally formed as an extension of the wall. |33 is a U-shaped loop |40 providing an aperture |4|. The left hand leg |42 of the loop |40 has its lower end` |8| at the same level as a shoulder |43, extending inwardly from near the top of the wall |33. The left hand leg |42 of the loop |40 is of such width as to fit between the inside surfaces of the walls |36, |38, and the outer surface of the leg |42 lies against the inside surface of the wall |32. The leg |42 may be provided with a tongue |82 extending laterally therefrom, through an aperture |83 in the wall |32, the tongue having its end bent over against the wall |32 to clamp the loop |40 to the wall |32.

Detent means |44 .is provided for cooperation with the aperture |4| and a conductor terminal which may be disposed therein. The detent means 44 includes a generally semi-cylindrical protuberance |45, and also in other respects the detent means |44 is identical with the detent means 36 of Figure 2. Upward motion of the detent means |44 is limited by engagement with the shoulders |43, |8|. Detent means |46, having a semi-cylindrical protuberance |41 is provided, this detent means being otherwise also identical with the detent means 45 of Figure 2. The detent means |46 is cooperable with apertures |48, |49 and a conductor terminal insertable therethrough. The apertures |48, |49 are formed by recessing the longitudinal abutting edges of the wall halves of the walls |34, |35. The upper inside surface of the arch-shaped bight of the detent means |44 is related to these apertures in the manner already described in connection with the detent means 36 and the apertures 43, 44 of the terminal post 22 of Figures 1 through 6. A spring |50 is provided for biasing the detent means |46, |44 similarly to the acticn 0f the spring 50. The lower end of the spring |50 engages an insulating plate |5|.

The wall halves |38, |39 are provided with extensions at their lower ends bent at right angles to these walls to form feet |52, |53. The wall halves |88, |81 are similarly provided with feet, only one of which |88 is visible (see Figure 10).

The wall |82 of the body portion of the terminal post |88 is extended vertically upwardly, beyond the top of the loop |88 and has integrally formed therewith a bracket |55 extending at right angles from the wall |82. The bracket |55 serves to hold a cartridge fuse |58 having terminal ferrulesi 51, |58. The bracket |85 comprises a horizontal portion |58 provided with spaced webs |80, |5|, in the form of flanges at the margins of the vertical and horizontal parts of the bracket |55.

Pivotally depending from the horizontal part |58 of the bracket is a bell crank lever |82 having a downwardly extending arm |88 and a generally horizontally extending arm |84 slightly downwardly inclined to allow for some freedom of movement between it and the part |58 of the bracket. The bell crank |52 is pivoted to the horizontal part |58 of the bracket by providing a tongue |55, struck out from the arm |58, the tongue |55 passing through an aperture |55 in the horizontal portion |58 of the bracket and suitably bent over to retain the bell crank pivoted to the horizontal portion |58. The bell crank lever ||2r is biased in a counterclockwise direction, as viewed in Figure 8, by means of a helical spring |51, one end o! which bears against the underside of the arm |54 and the other end of which bears against the upper side of a lever |58. I

'I'he lever |58 has a portion |58 extending upwardly at right angles thereto and provided with a tongue passing freely through an aperture |1| in the horizontal part |58 of the bracket. The tongue |10 is suitably bent over to prevent disengagement of the lever from the bracket. In the position of vthe parts as shown in Figure 8, the bent part of the tongue |10 is out of contact with the upper surface of the horizontal part |59 of the bracket.

'I'he oppositely disposed faces of the arm |58 of the bell crank lever and of the lever |58 may be provided with generally cylindrical protuberances |18, |14, desirably struck out from the bodies of these parts, to serve as seats for retaining the spring |51 in position.

The underside of the lever |58 is shown in abutment with the upper end of the fuse terminal |51, and the spring 51 biases the lever |58, counterclockwise and bodily downwardly, against the fuse terminal, thereby biasing the other terminal |58 of the fuse downwardly against a contact |15. The spring |51 also biases the bell crank lever |52 in a counterclockwise direction, thereby causing the inside surface of the arm |58 to engage the left hand cylindrical margin of the ferrule |51 to bias the right hand cylindrical surface of the ferrule |51 against the seat formed by the margins of the spaced webs |50, |5| of the bracket |55, to hold the ferrule |51 against lateral displacement.

The end of the lever |58 isfhere shown as disposed freely through an aperture |12 in the arm |58 of the bell crank lever. The aperture |12 is longer verticaly than the thickness of the lever |88 and in the position'of the parts shown in Figure 8 the upper and lower surfaces of the lever |58 are out of contact with the upper and' lower ends of the aperture |12, thus permitting the spring |81 to freely bias the lever |58 against the top of the ferrule |51 and also permitting upward movement of the lever |58 to remove the fuse |55. When the fuse is removed the end of the lever |88 engages the lower end of the vor insertion of the fuse. The fuse may also be removed by moving the terminal |51 against the bell crank arm |88 thereby disengaging the right hand surface of the terminal |81 from its seat on the liianges |88, |8|, the terminal |51 being then i6 moved laterally at right angles to the iirst movement.

The contact |18 is, in this instance, identical with the contact 84 of the embodiment of Figures l through 6, and the terminal posts |28, |28 are identical with the terminal posts 28, 2|. The terminal posts |28, |28, |88 are held to the insulating plate |5| by an apertured insulating plate (a spacer |11 being interposed, if desired) clamped by a metallic channel |18, in the manner already described in connection with the embodiment of Figures 1 through 6. The insulating plate |15 is also provided with an aperture, exposing the contact |15, and serving as a lateral seat for the fuse terminal |58.

The mode of assembly of the embodiment of Figures 1 through l2 will be evident from the foregoing description and what has already been stated in connection with the embodiment of Figures l through 6.

From the foregoing it will be apparent to those skilled in the art that the illustrated embodiments of my invention provide new and improved electrical connection means, readily and conveniently constructed and assembled, and accordingly, accomplish at least the principal 4object of my invention. On the other hand, it also will be obvious to those skilled in the art that the illustrated embodiments of my invention may be variously changed and modiiied, or features thereof, singly or collectively, embodied in other combinations than those illustrated, without departing from the spirit of my invention, or sacricing all of the advantages thereof, and particularly, that my invention is not limited to conductor terminals of the plug type, but that the term conductor terminal is to be considered generic, including for example merely a portion of the conductor wire itself, and that accordingly, the disclosure herein is illustrative only, and my invention is not limited thereto.
